Question

我在ubuntu 14.04上。我正在运行anaconda，我使用conda命令（根据this post）使ipython笔记本中的python 2和python 3都可用。但我刚刚卸载了anaconda并在virtualenv中单独安装了ipython，jupyter和notebook。现在，当我尝试创建一个新笔记本时，我收到以下错误。正如你在最后一行中看到的那样，似乎仍然指的是用anaconda创建的内核，因为我卸载了anaconda后显然不再存在。

有人可以帮我解决这个问题吗？非常感谢。

Answer 1

运行jupyter kernelspec list，它应该告诉你kernelspecs的安装位置。您需要删除现在不正确的文件夹。

或者，按照in the IPython docs所述，使用您现在安装的ipython安装新的kernelspec。这将取代已为该版本的Python安装的kernelspec。

卸载anaconda
